Hejnar Photo – Gitzo Head Arca-Swiss Conversion Clamp (Model FG3)

Arca-Swiss Conversion Quick Release Clamp for Gitzo Quick Release Plates

The Hejnar Photo FG3 Conversion Clamp is a precision-engineered upgrade designed to bring full Arca-Swiss compatibility to Gitzo Quick Release Plates. This 2.375-inch clamp mounts directly onto your proprietary Gitzo quick-release system, allowing you to seamlessly integrate professional Arca-type plates, L-brackets, and rails into your workflow. Proudly CNC-machined in the USA from solid 6061-T6 aluminum, it provides an unyielding, high-performance foundation for demanding photographic environments.

Detailed Installation Instructions

Modernize your Gitzo ball head system in just a few simple steps:

  1. Align the Pins: Position the FG3 clamp over your Gitzo plate structure, making sure to align the built-in anti-rotation slot with Gitzo’s locating pin.
  2. Select Your Hardware: Determine if your mounting equipment requires the pre-installed 3/8"-16 threads or the 1/4"-20 / M6 countersunk options. Remove the stainless steel reducer bushing if a wider connection is required.
  3. Secure the System: Tighten and fasten the clamp securely into place. For long-term field reliability, a drop of medium-strength thread-lock (such as Loctite Blue) is highly recommended.

Quick Overview & Key Features

  • Universal Standard: Enables full compatibility with Arca-Swiss style plates from Hejnar Photo, RRS, Kirk, Wimberley, Markins, and more.
  • Advanced Jaw Design: The tongue-in-pocket engineering prevents the moving jaw from hinging backward, ensuring monolithic clamping force while blocking out field grit.
  • Captive Knob: The one-piece ergonomic aluminum knob stops at its maximum opening and cannot be lost or unthreaded in the field.
  • Zero Rotational Play: Milled registration channels and the dedicated anti-twist pin slot lock the clamp permanently in place for absolute stability.

Comprehensive Product Description

The Hejnar Photo FG3 Arca-Swiss Conversion Clamp is the definitive solution for photographers who demand the precision of Gitzo engineering combined with the modular flexibility of the Arca-Swiss ecosystem. By converting your quick-release setup, you bypass the inherent limitations and limited plate options of proprietary Gitzo quick-release systems, ensuring your gear adjustments translate perfectly to your final capture.

This clamp is a new product design engineered for unyielding stability under professional equipment loads. The advanced "tongue-in-pocket" design protects internal threaded parts from dust, sand, and grit, while keeping the jaws perfectly aligned with the geometry of your plate. Whether you are conducting critical architectural work or conducting high-magnification macro photography, this clamp maintains a monolithic connection that factory components simply cannot match.

Proudly made in the USA, this component provides the structural integrity and technical excellence that defines Hejnar Photo hardware. It is a robust, intelligent investment that modernizes your existing support architecture for ultimate reliability across all your tripod and monopod rigs.
